Which KPI would best link process quality to cost and customer satisfaction?

• A. Defect rate
• B. First-pass yield
• C. On-time delivery
• D. Cycle time

Answer: (A)

Focusing on a KPI that directly shows quality problems and their financial impact is key. Defect rate measures the proportion of units with defects, so it directly signals quality issues. When defects occur, costs rise through rework, scrap, returns, and warranty work, and customer satisfaction tends to drop due to receiving faulty products. Conversely, lowering defect rate reduces these costs and improves the customer experience. The other metrics are useful but don’t tie quality to cost and satisfaction as directly. On-time delivery concerns timeliness more than product quality, cycle time looks at speed, and first-pass yield is related to quality but still indirect in terms of the explicit cost consequences and customer perception. Defect rate gives the clearest link between process quality, cost, and customer satisfaction.
